By the Numbers

Basement Suite ROI & Market Data

Kelowna's rental market makes secondary suites a smart investment.

Locally Coordinated

200+ secondary suite permits issued annually by the City of Kelowna, reflecting growing demand for rental housing and mortgage-helper income. The City actively encourages legal suites as part of its Official Community Plan and Housing Strategy (City of Kelowna Building & Permits Department, 2024).

$1,400–$1,800/month rental income potential for a 1-bedroom legal suite in Kelowna, and $1,800–$2,500+ for a 2-bedroom suite depending on location and finish level. That's $16,800–$21,600+ annually — a significant offset to mortgage costs (CMHC Rental Market Survey, Kelowna CMA, October 2024).

Legal suite requirements under BC Building Code Part 9 and City of Kelowna Bylaw No. 12375 include: fire separation (45-minute rated assemblies between dwellings), interconnected smoke/CO alarms, a second means of egress from each bedroom (clear opening ≥ 0.35 m²), sound control (minimum STC 50 between units), one off-street parking stall, and a hard-surfaced path to the suite entrance.

6–12 week typical build timeline for a full basement suite renovation in Kelowna, including permit processing (2–4 weeks), rough-ins, insulation, drywall, finishes, and final inspections. We manage the entire process — drawings, submissions, inspections, and handover.

“We are pleased to endorse and recommend Nailed it Developments for your next residential project. Ashton and Richard along with their crews did a wonderful job of our extensive renovation. Our major parts of the reno included two full bathrooms, and a complete kitchen. Two bedrooms and living areas were updated as well. Their staff led by Evan and Alex demonstrated professionalism, clear communication, and a strong commitment to quality. They provided a detailed project plan and maintained transparency about costs throughout the process. Their attention to detail and dealing with subtrades was comforting. They were extremely accommodating considering we lived in the house as the project was done. Without them we could not have accomplished this project. Thanks again, Carson and Liz”

“Ashton came out to look at a possible reno at a new home for us. He was on time, knowledgeable, but most importantly, I felt like he wanted us to understand the job and what we getting into. Ultimately, we chose to not buy the house as the project was bigger than we thought -- but we are happy that Ashton helped us out.”
